asiva@google.com b4d9e0d620 Auto create ApiLocalScope before calling native functions, this ensures that 
native functions do not have to call Dart_EnterScope/Dart_ExitScope
when they callback into the VM.

Remove Dart_EnterScope/Dart_ExitScope calls around native functions in 'bin'
directory.

zra@google.com f219f81b14 Begins implementation of ARM neon instructions. 
Just adds the vadd instruction, but also changes the
arm assembler to expose the Q registers rather than the
D registers. Q0 = D1:D0 = S3:S2:S1:S0. This is similar
to how ia32 and x64 use only the xmm registers for
floating point.

regis@google.com 05e2ba9540 Support FrameLookup vm test on ARM, requiring among other things: 
Maintain a separate top_exit_frame_info for simulated frames and use it to
verify that longjumps are safe.
Make sure unwinding of scopes works in the presence of a simulator.
Support inline allocation of objects.
Support checking of inline cache and instance calls.
Support subtype test cache.
Support (some) equality checks.
Support for (some) conditional branches.
Support for pool pointer setup in stubs.

zra@google.com f6da1febeb Drops into Simulator Debugger only in a session that is already interactive. 
This change backs out an earlier change to the disassemblers that
made them return false if an instruction couldn't be decoded.
This was used in the simulator debuggers for arm and mips to avoid
executing an instruction that couldn't be decoded.

Instead, now when an unknown instruction is encountered in the simulator,
if the simulator is running interactively, we drop into
the debugger, and otherwise die. We detect that a simulator is
running interactively by setting a flag if we enter the debugger
for a user set break point.
